Different permutations of the single and the two-fold dam-break flow have been investigated using the mesh-free smoothed-particle hydrodynamics and the experimental setup. The free-surface deformation in the case with the wet bed for five different downstream water heights has been investigated and respective numerical and experimental results were presented. The results demonstrate that the increase of the water height over the wet bed leads to the reduction of the flow front velocity. Effect of considering or omitting the dam gate during the numerical simulation has also been examined, which proves that the simulations including the dam gate show improved agreement with the experimental results. Influence of the three-dimensional cubic, triangular, circular and square cylindrical obstacles and their position on flow characteristics has been investigated. As the distance between the triangular obstacle and the gate increases, a bore is created at the position closer to the top of the triangle. In addition, it is found that larger force is exerted on the circular cylinder in comparison to the square cylinder.

互易湿床溃坝流越过障碍物的实验和 SPH 研究

使用无网格平滑粒子流体动力学和实验装置研究了单折和双折坝溃流的不同排列。研究了五种不同下游水高的湿床情况下的自由表面变形，并给出了各自的数值和实验结果。结果表明，湿床上水高度的增加导致流动前沿速度的降低。还研究了数值模拟过程中考虑或省略坝闸的影响，这证明包括坝闸的模拟与实验结果的一致性有所提高。三维立体的影响，三角形，研究了圆形和方形圆柱障碍物及其对流动特性的位置。随着三角形障碍物与闸门之间的距离增加，在靠近三角形顶部的位置会产生一个孔。此外，发现与方形圆柱体相比，圆柱体受到更大的力。
